Add ReleaseRun CLI to OSS and Dependency management

[Matheus-RR]

Description

Adds ReleaseRun to the OSS and Dependency management section — a CLI tool and GitHub Action that scans dependency files for EOL dates, CVE risk, and health grades.

What it does (distinct from existing tools in this section):

• Checks package.json, requirements.txt, Cargo.toml, go.mod, composer.json, package-lock.json etc.
• Reports EOL status (end-of-life date proximity) in addition to CVEs — filling the gap between CVE scanners and version managers
• Returns letter grades (A–F) with severity-weighted scoring
• GitHub Action available for CI integration: Releaserun/releaserun-action@v1

Ecosystems covered: Node.js, Python, Go, Rust, Ruby, PHP, and more
